APPARATUS FOR DISCHARGING COLLAPSIBLE TUBES.

Specification of Letters Patent.

Patented Mar. 12,1912.

Application filed September 1, 1910. Serial No. 580,031.

To all whom it may concern:

Be it known that I, Roy L. SMITH, a citizen of the United States ofAmerica, residing at Lexington, in the county of Fayette and State ofKentucky, have invented new and useful Improvements in Apparatus forDischarging Collapsible Tubes, of which the following is aspecification.

This invention relates to devices for discharging collapsible tubes, andit has particular refercnceto a device of this class adapted to be usedin connection with shaving brushes for the purpose of discharging thecontents of a collapsible tube containing a soap preparation in paste orcream form directly into the shaving brush, the discharging apparatusbeing associated with the brush handle.

With this and other ends in view which will readily appear as the natureof the invention is better understood, the same consist-s in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaim may be resorted to when desired.-

Figure l is a perspective view of a tubular brush handle forming part ofthe invention, a portionhaving been broken away. Fig. 2 is a perspectiveview of the container used in connection therewith, showing one form ofthe device for collapsing the container applied thereto. Fig. 3 is aperspective view, showing the brush head detached. Fig. 4: is aperspective view illustrating the preferred form of the collapsingdevice for the container.

The brush handle which forms a part of the improved device consists of acylindrical tube 1, one end of which is closed, as shown at 2, theopposite open end being internally threaded-for a short distance, asseen at 3. The tube 1 is provided with diametrically opposite slots 4extending from the open end in the direction of the closed The brushhead 5 has a reduced portion 6 end of the aperture 7 is internallythreaded at 11 to be engaged by the threaded portion 12 of thecollapsible tubewhich ordinarily receives a cap or closure, the latter,however, being not shown in the drawing. The brush head 5 is alsorovided with an annular groove 13 in which the bristles 14 may besecured in any suitable convenient and well known manner.

A brush collapsing device or ke A is provided, the same consisting inits simplest form of a key member including a shank 15 having at onecnda stationary or integral head 10 and at the opposite end a detachablehead 17 which may be threaded upon the shank. The latter is alsoprovided with a slot 18 extending from the stationary head 16 throughthe entire length of said shank.

In the operation of this form of the invention, the collapsible tube 10containing a suitable soap preparation in paste or cream form isthreaded into the brush head which is meanwhile detached from thehandle. The tube is now inserted into the handle with which the brushhead is connected by the reduced threaded portion 6 engaging theinternally threaded portion 3 of the handle, a few turns of the brushhead being sutlicient to make the connection. The key from which thehead 17 has been detached is now inserted through the slot 4 of thehandle in such a manner as to straddle the compression end of thecollapsible tube, after which the head 17 is restored to the key whichis thus secured in position. Itwill now be obvious that by slightlyturning or rotating the key about its axis the collapsible tube will begradually wound u on the key, thereby expelling the contents ot the tubewhile collapsing the latter, the contents being expelled within-thebristle portion of the brush which may now be used for latheringpurposes. It is obvious that a very slight turn of the key will suf ficeto expel the requisite shaving preparation, and t e amount of ortion ofthe be very soon ascertained by practice. In

this manner the soap preparation may be utilized in a cleanly, sanitaryand economitwo compression rollers 21 which are mounted for rotation insaid side pieces. The latter areprovided adjacent to their apices orupper-ends with apertures 22 for the passage of the key or compressionmemher A which is of the exact construction hereinbefore described. Thecollapsing end of the tube or container 10 is inserted be tween therollers of the compression frame prior to its insertion into the tubularhandle member 1, after which the key is applied to the collapsible tubethrough the apertures 22 of the compression member with which it is thusconnected; The rollers 21, when the key is rotated, will assist incompressing I the collapsible tube and in' expelling the contents of thelatter.

From the foregoing description, .taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood.

' The device may be made of any suitable material, such as metal or hardrubber, and. of any proper dimenslons to recelve or to operate inconnectionwith collapsible tubes or containers of standard size. Whenthe collapsible tube is empty, the parts may be readily disassembled,after which the empty tube may be removed and replaced by a newcontainer.

The device is simple, convenient for home or traveling use andabsolutely clean and sanitary.

Having thus described the invention, what is claimed as new, is

A tubular member having longitudinal slots in opposite sides thereof, acollapsible container within the tubular member, a collapsing deviceincluding a frame compris ing approximately triangular side memberswhich are curved to fit within the tubular member and having aperturesnear their upper ends, a pair of compression rollers supported forrotation at the lower ends of said side members, and a key including abifurcated .shank adapted to engage the apertures of the side membersthrough the slots in the tubular member and to straddle the collapsiblecontainer, said key being provided at one end with a fixed head and atthe other end with a detachable head threaded upon the bifurcated end ofthe key. In testimony whereof I afiix my signature in presence of twowitnesses.
